UNITED STATES" PHILIP H. FIELDING,

PATENT OFFICE.

on NEW YORK, N. Y.

SPECIFICATION forming part of Letters application filed April 2, 1900,

To all whom it may concern:

Be it known that I, PHILIP H. FIELDING, a citizen of the United States, residing at the city of New York,borough of Manhattan,State of New York, have invented certain new and useful Improvements in Receptacles for Incandescent Lamps, of which the following is a full, clear, and exact description.

This invention relates to receptacles for incandescent electric lamps, the object being to provide a device which can be attached to a wiring-molding or. other foundation and connected with the wires of the circuit in a simple manner and which when so mounted and in operative condition all contacts will be entirely covered and the risk of a fire or shocks to persons avoided.

In general the invention consists of a receptacle comprising two parts, an inner part and an outer part, the latter acting as a shield for the former and all contacts being connected with the inner part and being so located that the wires of the circuit can be stripped of their insulation for a short length and connected with said contacts, thus avoid.- ing the operation heretofore necessary of making half-splices and leading the branches to the contacts.

In the accompanying drawings, Figure 1 is a plan of my improved receptacle applied to a wiring-molding. Fig. 2 is a section of the same with parts in elevation and showing the lamp in position. Fig. 3 is a side elevation of the inner part of the receptacle. Fig. 4 is a section on line 00 a of Fig. 3, and Fig. 5 is an end view of'the receptacle.

The receptacle is made of elongated shape intended to be placed lengthwise against the face of a wiring-molding, (indicated by A ;)but the shape is not an essential feature of the invention, since a circular shape may be. adopted Where the conditions are different.

The receptacle is in two main parts-an inner part and a shielding or outer part. The inner part is indicated by a. It is a block of porcelain or other suitable insulating material having a central raised portion a and lateral ears a providedwith perforations for fastening-screws. The block has attached to it two metal brackets 12 and I), each carrying a binding-screw b exposed on the opposite sides of the block. The bracket 1) is seatent No. 660,154, dated October 23, 1900. SerialNo. 11,121. on model.)

I cured to the block by a central vertical bolt 5 having a contact-head b projecting upward. The bracket b is secured to the block by two screws 19 which also pass through the flange of a metallic threaded socket b into which the base of the lamp screws. The socket and the bracket 1) are therefore electrically connected, while the bracket and the center contact 19 are electrically isolated from them by the fact of a large opening in the bottom of the socket and the sinking of the bracket 1) in the block.

The outer part of the receptacle (indicated by c) is in the nature of a cap or cover, also of porcelain or other insulating material and consisting of a central cylindrical part 0, adapted to surround the lamp-socket b and the projection a and lateral ears perforated for fastening screws and adapted to cover the cars a of the inner part a. When so adjusted, as shown in Fig. 2, both the inner and outer parts are secured in place by the screws cl, which pass through the perforations in both of said parts. I

Since these receptacles are most generally used in connection with Wiring-moldings, I

make the width of the inner part of the re-' ceptacle agree with the distance between the grooves in the molding, so that when the receptacle is attached to the molding the inner part will just fill the space between the grooves, and the binding-screws b will stand immediately above or opposite the respective grooves.v To connect the two wires (indicated byf and g) with the respective screws, I repleted, the receptacle presents a perfectly smooth exterior, all contacts being entirely covered and hidden by the cap.

Having described my invention, I claim 1. A receptacle for incandescent lamps,

consisting of an elongated block carrying at its middle a lamp-socket, and binding-screws exposed on each side thereof, the extremities of the block being perforated for fasteningscrews in combination with a cap or cover of insulating material having acylindrical portion surrounding the lamp-socket and the binding-screws, and extensions or ears covering the ends of the block, said ears being perforated in line with the perforations in the ends of the block, for the purpose set forth.

2. A receptacle for incandescent lamps, consisting of an elongated block carrying at its middle a lamp-socket and binding-screws exposed on each side thereof, the extremities of the block being perforated for fasteningscrews in combination with a cap or cover of tion surrounding the lamp-socket and the binding-screws and extensions or cars covering the ends of the block said ears being perforated in line with the perforations in the ends of the block, and a pair of line-Wires engaged by the binding-screws and running parallel to the said extensions and between which wires the fastening-screws pass for the purpose set forth.

In Witness whereof I subscribe my signature in presence of two witnesses.
